Rx7 Problems

[polishrotor]

I\'m from Australia and I recently purchased a 2nd generation RX7 (88 model). At first there was alot of oil leakage but all it needed was 2 seals and for now there seems to be no leakage. However the thing is that when the car starts it runs for a couple of minutes until it gets warm. Once the engine gets warm the rotary shuts down. You can start it a couple of times but it will keep on turning off. After a while it won\'t even start and you have to wait until the engine cools down b4 you can start it. So im asking if anyone could give me some information on what might be wrong with my Rotary and suggestions on what to do and how much it might cost. I would really appreciate it.
